Gentlemen, maybe alongside the Rhine or the Danube or the Loire there is convenient electric bicycle touring from powerpoint to powerpoint. But I still don't see another 30 miles on an electric bike when accommodation doesn't pan out on a day when you've perhaps already used even a little of a battery for 30 miles. A battery that can carry you 60 miles will very likely weigh as much as a loaded tourer's gear. Even a battery to carry you 30 miles weighs at least 7 or 8 pounds, very likely more. And remember, the cyclist, who may already be all in, is assumed to produce most of the effort, not the battery.
We've never actually determined how far a battery of xAh will carry a cyclist and camping or cycling holiday gear, among other reasons because those of us with electric bikes are far too sensible to run the batteries totally flat, which will wreck a LiPo battery in very short order.
But I've actually taken some ebike very-mini tours, in a country, Ireland, with an abundance of high quality bed and breakfast places, complete with government supervision and a bookings book available from any tourist bureau and a lot of news agents. But I've never written about those tours here because by the standards prevailing here, they're mickey mouse efforts. I call them Andre's World Tours of his Little Patch of the Back Country of West Cork. Some of them are within a radius of 30 miles, though the tour might stretch out to three days 60 or 70 miles because we investigate all the back roads, and stay off the main and secondary roads, which in main are dangerous and unpleasant. However, the country buses will take you and your bike, so on one tour to a town 60 miles away, we rode to an intersection with the main road 15 miles away, took the bus down the main drag to almost within sight of the town where we would stay that day, then took off on a trip around a peninsula, total days's journey 40 miles and some change; the point was that we knew all these roads, and how much they draw from the battery. This isn't what Tyreon is describing at all... For a start, my luggage is a bottle of water, a block of Bourneville chocolate, a credit card, a few sheets torn out of a bed and breakfast book, and a couple of pairs of clean underpants -- everything else I just buy and, since I take a shower every evening, I don't care if the over-sensitive think I sniff or the collar of my shirt isn't pristine, because I'm never away from home more than three days. Note further that I know all these small towns, and have the phone numbers of their local taxis on my phone, and that the landladies of the B&Bs I've stayed with before in an emergency will come pick me up. I don't even carry a spare tube; my entire tool kit weighs 68gr. I'm the absolute paradigm of the credit card tourer.
In short, ebike touring is possible if you're in civilization, if you know the area because you've cycled there before, if you aren't on a budget, if you're willing and able to plan ahead, if you're not ambitious at all (or your cycling companies have to be considered), and if there are plenty of alternative solutions if your plans fall through (never happened to me, but I'm a belt and braces man). Any other circumstances short of proper bike infrastructure and I suspect ebike touring could easily become a rod for your own back. I don't fancy schlepping a flat battery around when I'm already wiped by distance or heat or mishap.
I'm sorry to say, I think your enthusiasm for ebike touring is premature. It'll happen, eventually, but the time isn't here yet.
I'll start another thread so that we can share experience about the distance an ebike battery can reasonably be expected to carry you.
